Adults Adjustable LED Bike Helmet for Commuting and Road Biking

This bicycle helmet is designed for adults or youth/teen, with a suggested head circumference of 52.5-55.5cm (20.7-21.9 inches). To determine the correct helmet size, please wrap a measuring tape around your head, ensuring the tape rests 1.5cm above your ears and remains level around the circumference of your head.

The GTSBROS bike helmet with lights has passed CE and CPSC certification, combining a one-piece structure of EPS foam and high-density PC shells to ensure better shock absorption and provide safer protection. This high-quality cycling helmet is protective and ideal for urban commuting, cycling, scooter riding, skateboarding, as well as suitable for city, road, electric, and trek bikes.

Featuring a Dual Fit adjustable design, our road bike helmet for men and women includes a size-adjustable dial at the back of the helmet and side straps to fit different head circumferences. Simply turn the dial to adapt the built-in helmet framework for a perfect fit.

Additionally, our cycling helmet is designed with USB rechargeable front and back lights. While the front lights provide illumination, the rear lights offer higher visibility for the vehicles or people behind you, enhancing your safety on the city streets at night. The rear lights have four modes: constant, flash, slow flash, and warning flash, allowing you to easily adjust the lighting without removing the helmet.

To keep you cool and comfortable during a casual ride or a long day on your bike, this adult bicycle helmet has 14 vents with inside air-channels. The removable padding can be washed and provides optimal cushion for a comfortable, extended ride.
